2n3055 audio amplifier with transistor, Powerful audio amplifier with 2n3055
- C1 capacitor governs the low frequencies (bass), with the capacitance grows, the lower shorter intervals are increasingly high.
- Capacitor C2 regulates the higher frequencies (treble), with the capacitance grows, the higher frequencies are getting quiter.
- This is a class B amplifier, this means that the current must flow through the transistor end, even if there is no sign at the entrance. This current can be adjusted with the 500 Ω resistor trimmer.
- As this increase present, the sound of the amplifier is better, but the effect transistors are more heating. But if this deceases current, the transistors are not very warming, but the sound gets worse
